In a medium bowl, combine ingredients for meatballs into a bowl and mix thoroughly.
Spoon 1 Tbsp of mixture and roll between your hands to form a single meatball. Repeat until all of the mixture is used (makes approx. 28 meatballs). Set aside
In a small bowl, whisk together sauce ingredients.
Preheat a large 12" skillet on high heat and coat with cooking spray. Add meatballs and cook until lightly browned (around 2-3 minutes). Note meatballs do not need to be cooked fully at this point.
Add the small bowl of sauce ingredients to the skillet.
Simmer for 15 minutes, uncovered.
Top with cilantro and green onion, if desired
